`In the useV 'of-.my improved controlling i mechanism, it will be noted that. vwhen the operating handle 35 is rotated the internally threaded nut'member 31, engaging'the threads formed on the cylindrical portions 29 and- 30 or-the rods .24 and 25, will react against the shoulder. 39 of the frame through -tlie'sleeve member 40 and will thus cause the rods to siinultaneouslymove in opposite directions,thereby swinging the V-shipper members and V6 about their pivots 7 and Sinopposite directions and causing one of the friction'al controlling members `tov-be released while the other is applied,

consequently;- preventing the application of both the' clutches, and consequently the fast or slow feeds, simultaneously.

As a-result of myv improved construction, it will be noted that I havev provided `an i `improved, controlling mechanism for selec- 'tively operating a`plurality of clutches and which has'a` common operating element of improved -form which is readi-lyaccessible 'Y 4from the exterior ofthe machine frame for assembly. and adjustment'. Itr` will further benotedthat I have provided an improved rcontrolling mechanism of exceedingly-siniple, rigid, and compact construction, y.which lmayVV beapplied to amining machine of 25 standard Aform with a minimum of change and eXp ense.
